Most cell phones are built to prohibit repairs or upgrades by the owner. Instead the manufacturers seem to want to force us into buying new phones every two years. The Fairphone is different, using a modular design it can be completely disassembled, and parts can be easily swapped out or even upgraded.

Upgrading or replacing battery pack, SSD and other parts on Acer C720 Chromebook's
How many of us, if the trackpad on our laptop stops working, get frustrated, set the computer aside, and buy a new one? That costs money to replace the computer, more 'stuff' piles up, it disrupts our lives, but somehow it's easier to just replace than figure out how to fix it. Turns out this specific issue, the trackpad puzzlingly not working, could be easily fixed. In my case the battery pack had swollen pushing against the trackpad making it not work correctly. The swollen battery pack itself is very dangerous and I wouldn't have known of it otherwise. Further, the replacement was next to trivial and a lot cheaper and less disruptive than replacing the whole computer.
